Finally passed my NNP boards after failing twice — here's what worked

I'm not gonna sugarcoat it — I failed the NNP exam twice before I finally passed last month, and I want to share what actually made the difference because I wish someone had told me this stuff earlier. My first two attempts I was just reading Kenner & Lott cover to cover and calling it a day. Spoiler: that's not enough.

What changed everything was getting serious with an NNP practice test routine. I did timed question blocks every single day for six weeks — like 50 questions minimum, no exceptions. I also found a solid NNP study guide that organized the content by system (resp, cardiac, neuro, GI) which finally made the pathophysiology click for me. The exam is way more application-focused than I expected, not just recall.

My weak spots were pharmacology and fluid/electrolyte management — both showed up heavily. Anyone else prepping right now or recently went through this? Would love to compare notes on which topics felt most heavily tested and any exam tips that helped you stay focused during the actual 4-hour block.
